1. Explain why you can't fully test the lipase activity in the tube 5.

Measurement of lipase activity uses a decrease in pH. Since the pH in Tube #5 is already very low, it is difficult to tell if fatty acids are released.

Test tube #1 should have the highest activity because the pH is closest to the pH of the small intestine. Note: Some students might choose pH 9.0 but the intestine is closer to 8.0 and the enzyme is not activity at such high alkalinity.
